Many people ask me what sorts of things I work on.\u00a0 Well, here’s one of them you can download and run on your own!\u00a0 This is a graphics and code sample that co-developed to show off not only a novel new kind of volumetric effect, but also a new extension on some of Intel’s new CPU graphics hardware.<\/p>\n

This technique is called adaptive volumetric shadow maps.\u00a0 The base idea was developed by Marco Salvi who published a paper on it a little while back<\/a>.\u00a0 However, this version has been substantially improved by the use of a new feature of Intel processors called PixelSync<\/a> which allows one to do the volumetric shadowing effect with a constant-sized buffer and no depth slicing.<\/p>\n

The effect allows for self-shadowing on any kind of transmissive, volumetric media – such as smoke or hair simulations.<\/p>\n

You can download the sample, run it your own, and read more about it here:
